The Honda Ridgeline brake component utilizes a 7443 bulb size for the specific lighting application mentioned in the provided technical data. Information for the vehicle covers a span from 2006 through 2014.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Honda Ridgeline uses the 7443 bulb as the dominant brake light specification across its brake and outer brake positions for the 2006-2014 model years.
The 7443 is a dual-filament T20 wedge bulb rated at 12V with a 21W high filament and a 5W low filament, making it suitable for combined stop and tail light functions within a single housing.
The outer brake light position on the 2006-2014 Ridgeline also specifies the 7443, meaning both the standard brake and outer brake positions share the same bulb type across those years.
The center high mount stop light on the 2006-2014 Ridgeline uses the 168 bulb, a miniature T10 wedge type rated at 12V and 4.9W, which is a significantly lower wattage than the 7443 used in the outer positions.
For the 2017-2019 Ridgeline, the center high mount stop light specification changes to the 7440, a single-filament T20 wedge bulb rated at 12V and 21W.
The 7440 and 7443 share the same T20 wedge base and physical form factor, but the 7440 carries only a single filament while the 7443 carries two. Substituting a 7440 in place of a 7443 would result in the loss of one filament function.
The 168 bulb uses a T10 wedge base, which is physically smaller than the T20 base of the 7440 and 7443, making those bulb types non-interchangeable with the 168 socket.
All three bulb types specified for the Ridgeline, the 7443, 7440, and 168, conform to ANSI standards applicable in both the United States and Canada.
